WILLIAM WATTS, OF NEWARK, NEW JERSEY.

IMPROVEMENT IN STEAM-PUMPS.

Specification forming part of Letters Patent No. 39,852, dated September8, 1863.

To all whom it may concern,.-

Be it known that I, WILLIAM WArTs, of the city of Newark, in the countyof Essex and State of New Jersey, have invented certain new and usefulImprovements in Steam- Pumps and I do hereby declare that the t'ollowingis a full, clear, and exact description of the same, reference being hadto the aecompanying drawings, making a part ot'this specication, inwhich- Figure l is a perspective view ofthe pumping-cylinder of asteam-pump, with the valves attached thereto, the cap of one ot' thevalves being removed in order to show my improvement therein. Fig. 2 isa longitudinal verti-l cal section of my said improvement; and Fig. 3 isalso a longitudinal section ot' my said improvement, showing a differentbut equivalent form ot' device to accomplish the same results as inFigs. 1 and 2.

The same letters indicate like parts in all the tigures.

It is Well known that most, if not all, the steam-pumps in use are quitecomplicated as to the arrangement of their valves, and that there is notone in use in which Worn ordefective valves can be cheaply and readilyrepaired or replaced.

A steam-pump, of all devices, should be simple of construction, and thevalves not liable to detects or disarrangements, and when choked or Wornshould admit ot immediate access and replacement, if necessary. Theiremployment on ships, asin the recent sad case of the Monitor andPassaic. the first of which I'oundered at sea, and the latter, it isreported, at one time threatened inevitable abandonment on account ofthechoking of the pumpvalves, suiiiciently attests the necessity ofthe.simplicity and access ot' and to the valves above referred to.

In the gures, A is the'main body of the pump.

B B BB are bolts, which secure the caps C C C C to each ot' the fourvalve-chambers, as shown.

V, Figs. 1, 2, and 3, is the valve-seat. It is constructed in anyconvenient manner to contain either a metal-hinge valve. as shown in thegures, or a rubber-hinge valve, or one or more round disks, leather orrubber valves.- The valve seat V is formed to tit nicely into thevalve-chamber, and when the cap O and bolt B, with its accompanyingWedge W, is removed, said val ve-seat may be instantly slid into or outfrom its place in the said chamber. The wedge W, Figs. l and 2, restsupon the said valve-seat, as shown, and fornisa part of the bolt B, andthe projection I3 is a part ot' the main casting A, so that by theaction of the said Wedge upon P, as the bolt is drawn upon by the nut,the double purpose is accomplished, by means ota single nut and bolt,of' securing the valve-seat firmly in position, and also ot' tighteningthe cap C. In order, therefore, to examine the valveit is only:necessary to unscreW the nut on B and remove the cap. In order furtherto remove the valveseat containing the valve, it is only necessary toknock out the Wedge W, when the said valve-seat may be slid out, and anew one, it' required, may be slid in to replace it.

In Fig. 3 the toggle-joint T is employed as the equivalent for and inplace of the Wedge WV in connection With the bolt B.

Other modications of the device employed may be readily suggested, all,howevler,without affecting the character of the invention.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, ist 1. The combination o t the projection or bearingP with the Wedge W, bolt B, and cap C, substantially iu the manner andfor the purposes described.

2. The combination of the saidlivedge W with the valve V, substantiallyin the manner and for the purposes described.

WILLIAM WATTS.
